What type of signal is NOT typically used in fire control?

In the context of fire control, the type of signals traditionally used to communicate and coordinate actions include visual signals, sound signals, and whistle blasts. These methods are integral in conveying commands and ensuring that all personnel are synchronized during operations.

Visual signals, such as flagging or light signals, provide a clear means of communication over distances, especially where radios may not be effective. Sound signals, including the use of horns or calls, are also a vital way to relay information, especially in environments with noise that might hinder other forms of communication. Whistle blasts specifically can denote urgent commands or specific actions that need to be taken instantaneously.

Digital signals, while increasingly used in modern communication systems, are not traditionally employed in fire control tactics where immediate and direct forms of communication take precedence. This is because digital signals often depend on technology and equipment that may not be reliably available in all operational environments, especially in combat situations. Hence, digital signals are not typically considered a primary form of signaling in the context of fire control.
